CHAIN-HOLDER FOR TIRES.

Specification of Letters Patent.

Patented Nov. 26, 1918.

Application filed June 7, 1918. Serial No. 238,770.

To all whom it may concern:

Be it known that we, GEORGE B. N. Dow and JAMES F. CAVANAUGH, citizensof the- United States, residing at Manchester, in the county of Hillsborough, State of New Hampshire, have invented a. new and useful Chain-Holder for Tires, of which the following is a specification.

It is the object of this invention to provide novel means for securing an anti-skidding chain or like device to a vehicle tire, and to provide novel means for tightening the chain transversely of the tire.

Changes such as a mechanic might make, may be resorted to, within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figure 1 shows in side elevation, a portion of a vehicle wheel whereunto a device constructed in accordance with the invention has been applied, parts being broken away; Fig. 2 is a fragmental transverse section showing one of the yokes and attendant parts in plan; Fig. 3 is a section taken on the line 3-3 of Fig. 2.

Referring to the drawings, the numeral 1 denotes a hub carrying spokes 2. The numeral 3 marks a part of an anti-skidding chain or like device.

In carrying out the invention there is provided a rigid body 24: which may be of any desired shape, the body preferably being annular. Pivot elements 25 are mounted in the body 24. A U-shaped yoke 26 is mounted to swing on each pivot element 25 parallel to the body 24. In the arms of the yoke 26, a shaft 27 is mounted. The shaft 27 carries an eye 28 constituting a part of a stem 29, the eye being located between the arms of the yoke. The construction is such that the stem 29 may swing transversely of the body 24. The stem 29 has one or more longitudinally extended flat sides 50. One end of a loop 51 is threaded on the stem 29. A set screw 52 is threaded into the said end of the loop 51 and is adapted to engage the flat side of the stem 29. A rod 53 is threaded into the outer end of the loop 51,

By manipulating the loop 51 of the turn I buckle, the chain 3 can be tightened up. Because the yoke 26 can swing parallel to the body 24, and because the eye 28 and the stem 29. can swing on the shaft 27 transversely of the body, the device will accommodate itself readily to the chain 3 and hold the chain tightly and securely in place.

Having thus described our invention, what we claim as new and desire to protect by Letters Patent of the United States is 1. In a. device of the class described, a central body; pivot elements carried by the body; yokes mounted on the pivot elements to swing parallel to the body; turnbuckles having their inner ends mounted on the yokes to swing at right angles to the body; and attaching means carried by the outer ends of the turnbuckles.

central body; pivot elements carried by the body; yokes mounted on the pivot elements to swing parallel to the body and including outstanding arms; shafts mounted in the arms; stems having fiat sides and having their inner ends mounted on the shafts between the arms to swing at right angles to the body; rods; attaching means assembled with the outer ends of the rods; loops threaded in opposite directions on the stems and on the rods; and clamping devices carried by the loops and engaging the fiat sides of the stems.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two witnesses.

FRED E. WAY, ALLIE J. OAVANAUGH.
